Best Install Location for 3.8.4 and 4.0 CMS
 

I am trying to plan the most effective layout of my VB4 CMS for management and being SEO friendly. I am inclined to install on the root directory as opposed to a directory such as /forum. I will use the content.php for the site home page. I am not sure what weight it has weith search engines for the site homepage to be located at site.com/content.php compated to site.com/forum/content.php . So installing on the root places all content and VB folders on the root. I have found it easier to manage (at least for my limited understanding of this topic) to have everthing in a directory like folder as then everything in that folder belongs to VB. When installed on the root there are other folders and a CP that are there as well.

Is there a recommendation for this and is it know how this is might effect search engine indexing and ranking.

Just want to get off on the right track setting up the CMS. I am installing 3.8.4 and will hopefully be able to upgrade to the CMS and not break the install of the forum. I am importing my users from another forum into 3.8.4 getting ready for the CMS.

Any tips are appreciated.
